CME Analysis Information (for CME activity ID: 2024-04-21T15:37:00-CME-001)
Catalog: M2M_CATALOG Data Level: 0 (0=real-time, 1=real-time and checked by supervising forecaster, 2=retrospective science level data analysis) Use as primary measurement: true Measurement Technique: SWPC_CAT Speed (km/s): 510.0 Speed measured at height (Rs): 20.6 Type: C Direction (LON/LAT in HEEQ): 15.0/ -56.0 Half Angular Width (degree): 22.0 Minor Half-width (degree): None Entered Tilt (degree): None Entered Time@21.5: 2024-04-21T21:32Z Info/Session URL: None Entered Note: Measurement made with only SOHO LASCO C3 imagery, as the CME was deflecting in C2 and not reliably trackable until it settled in the C3 FOV, alongside a data gap in STEREO COR2A. Initial lat/lon were based on the observed EUV source, and the deflection to the south and east was roughly estimated on the behavior of very similar CME 2024-04-22T06:12Z which featured all coronagraphs for triangulation. As such, some variance in the true lat/lon may be present with only one coronagraph measuring this fairly central longitude, with good confidence in the high southern latitude out of the ecliptic plane. No Notification has been sent for this activity yet. |
